Issue Summary:

General Motors’ new-design pump-and-rotor assembly for 1994 and up 4T60-E models must be used with the tapered rotor because of some passage changes in the pump.

We have information on retrieval of Nissan diagnostic trouble codes – how to receive the signal from the A/T control unit and to indicate a detected fault by illuminating the malfunction indicator lamp (MIL).

General Motors has new-design solenoids for the 4T80-E, so we are showing the ways to identify them. Previous-design solenoids no longer are available.

Bind-up in reverse and 3rd and/or wrong-gear starts in the Ford 5R55E may be caused by a crack in the inner race for the center-support caged needle bearing.
